Corey needs 24 boards that are 47 1/2 inches long.A. how many feet of boards should he buy? explain.
B. If you can only buy 8-foot boards, how many should he buy?explain

Answers

Answer with explanation:

Number of boards need by corey =24

Length of each board is $47 (1)/(2)\n\n=(95)/(2)$

Length in inches of board that corey should buy

$(95)/(2)* 24\n\n=95*12\n\n=1140$ inches

1 foot=12 inches

$(1)/(12) \text{foot}=1\text{inches}\n\n(1140)/(12) \text{foot}=1140\text{inches}\n\n95\text{foot}=1140\text{inches}$

So, Length in feet of board =95 foot

Length of each board = 8 foot

Total Length in feet of board =95 foot

So, number of boards that corey should buy

$(95)/(8)\n\n=11(7)/(8)$

=Approximately 12 Boards

A. 95 feet
B. 12, because that would get you 96 feet of board, and if you only got 11, then you would only have 88 feet of boards which is not enough.

1=4，2=8，3=24，4=? please

Answers

Answer is 4 because 1x4 =4 , 2x4= 8 ... and so on because that is the really thing that only makes sense

these are all false statments but it should be written like this:
(1:4),(2:8),(3:24),(4:?)
the pattern is like this:
the first number in each set of parenthasees is 1,2,3,4,5...
the 2nd number is gotten by multiplying the first number times the previous term's 2nd number

so
(1:4),(2:8)
4 times 2=8
(2:8), (3:24)
8*3=24

then
(3:24),(4:?)
24*4=?=96

the question mark is 96

The length of a rectangle is 3 inches more than its width, and its perimeter is 22 inches. Find the width of the rectangle

Answers

The width of the rectangle is 4 inches.

What is perimeter of rectangle?

The formula for the perimeter of a rectangle is, P = length + breadth + length + breadth.= 2(length+ breadth)

Given: perimeter= 22 inches.

Let the width be 'b'

length= b+3

Perimeter of rectangle= 2(l+b)

22 = 2(b+3+b)

11= 2b+3

11-3=2b

8=2b

b=4 inches

So, length= b+3= 7 inches

Hence, the width of rectangle is 4 inches.

one thing that may help is the use of diagrams. See the attached photo.

To solve you need two equations.

2w + 2L = 22
L = w + 3

2w + 2(w + 3) = 22
2w + 2w + 6 = 22
4w + 6 = 22
4w = 16
w = 4

L = w + 3
L = 4 + 3
L = 7

What is 1 7/8 Times 2 1\3

Answers

We need to convert the mixed fractions into improper fractions.

1*8 = 8
8+7 = 15

15/8

2*3 = 6
6+1 = 7

7/3

Now we can finish and multiply

$(15*7)/(8*3)$

15*7 = 105
8*3 = 24

Simplify 105/24

105/24

24*4 = 96

105 - 96 = 9

4 is the whole number, and 9 is the numerator.

4 9/24

Simplify that,

9/3 = 3
24/3 = 8

4 3/8

Answer: $4(3)/(8)$

1 7/8* 2 1/3
= 15/8* 7/3
= 35/8
= 4 3/8

The final answer is 4 3/8~
